The PSP has gone through 3 revisions in three years and a confirmed fourth one is on the way (although we dont know the date we can be pretty sure its going to be next year).......if that doesnt spell the doom of one platform I dont know what does.
One thing that is sure though that with horrible ends come new beginnings and as such sony should learn from the mountain of mistakes they made with the psp. One very important one is to make actual handheld games and not gimped console games.....
All in all it was a valient effort by the lil guy but its time is over.
N64 is the ONLY console of the fifth generation!!!
